Police in Miami are investigating an officer who shot an unarmed black man who was an autistic man’s caregiver and video proof shows the man was complying with the officer.

Police were responding to reports of a man threatening to shoot himself on Monday, North Miami Assistant Police Chief Neal Cuevas told The Miami Herald.

Officers arrived to find 47-year-old Charles Kinsey, a therapist who works with people with disabilities, according to WSVN-TV. His 27-year-old patient reportedly ran away from a group home. The therapist claimed he was trying to return his patient to the facility.

Police ordered Kinsey and the patient, who was sitting in the street playing with a toy truck, to lie on the ground. The video shows Kinsey lying down and putting his hands up while trying to get his patient to comply.

“Sir, there’s no need for firearms,” Kinsey said he told police before he was shot, according to WSVN. “It was so surprising. It was like a mosquito bite.”

Kinsey said he was more worried about his patient than himself during the incident.

“As long as I’ve got my hands up, they’re not going to shoot me. This is what I’m thinking. They’re not going to shoot me,” he said. “Wow, was I wrong.”
